What is a Sound Processor?

The audio processor is the heart of most modern sound equipment. It powers a number of audio-related functions, from on-device EQs to voice recognition and active noise cancellation. It can also help extend battery life and prevent devices from overheating and breaking down.

A digital signal processor (DSP) enables powerful, yet power-efficient audio processing. These chips are available in a wide range of prices, performance points, and sizes from tiny low-power chips for smart speaker voice recognition to multi-channel processors in cars and professional studio gear.

Different DSPs optimize different parts of a digital signal chain to achieve the desired results. Channel EQ, for example, adjusts the tone of a single input signal coming into a mixer to balance offending frequencies while turning up pleasant ones that need accentuating. The same is true for a PA system's EQ, which optimizes the overall output of a speakers to compensate for room acoustics that might create peaks and nulls in the sound.

Reverb, echo, and delay effects add presence and ambience to a musical signal by imitating sonic reverberation in a room. They come in all sorts of flavors, from "slap back" echo, which echoes a single sound and plays it back again with a short delay time, to reverbs optimized for bass or vocals.

Other kinds of effects allow you to manipulate the sound in other ways, like a modulation processor, which enables psychedelic swirling reverbs and other sounds that can be applied over an entire song. These are common on outboard signal processors and some mixers, but they're not always necessary for most applications.

Digital signal processors, sometimes referred to as sound processors, are the new wave of audio enhancement. Many of today’s most advanced smartphones, headphones, smart speakers and even the new Amazon Echo speakers use DSP technology to enhance their performance.

A sound processor can strip away the pre-processing and speaker shaping limitations of your factory system, which often leaves you with a muddy sound that isn’t quite what you were expecting when you first got into your vehicle. It will provide you with a clean signal that is designed to be sent to aftermarket amplifiers, speakers and subwoofers, making it easy for you to hear the music you love.

If you’ve ever heard a high-end system in a showroom, you know that the soundstage is very impressive. That’s because a professional has carefully tuned the speaker positions to deliver a realistic image of each instrument and performer, resulting in a soundstage that spans the entire windshield.

That’s why it’s important to invest in a good quality sound processor or equalizer before installing an amplifier and speakers. Whether you’re looking for a simple upgrade or an all-in-one setup, the addition of a sound processor can dramatically improve your listening experience and give you a more immersive music experience in your car or truck.

Most sound processors come with a number of input and output channels that can be configured to store a variety of different system configurations. That means you can set a tune for your own seat, a tune for when you have friends in the back or another tune for when you’re driving on the highway with the top down.

A speaker processor is a small box that takes signal from various inputs and manipulates them to make your vehicle's speakers sound the way they were designed to. That means you'll hear better sound and a much better overall volume.

There are three types of speaker processors. One is dedicated to a single system, another is software-based and the third is a multi-function unit.

The dedicated loudspeaker processor first appeared around two decades ago and was usually rackmounted to optimize the performance of a specific speaker system. It typically provided input level protection, split a full-frequency signal into band-limited signals for bi- or triamplified systems and performed equalization to correct for the acoustic characteristics of speakers or cabinets.

Many of these models offer a host of other functions, including input level detection and protection, delay circuitry for time offsets between speaker components, and frequency response curve adjustments to match the acoustic characteristics of a room. Some of these devices include a PCMCIA slot for storing and recalling settings.

Dedicated loudspeaker processors are typically very affordable and are an excellent option for those looking to install a simple, high-performance sound system. Some of these systems also include a range of features that are valuable for the live sound operator, such as user-defined presets and filtering that can be easily controlled by the operator on a computer.

The Bose CSP Series is a family of commercial sound processors that work with a broad array of Bose loudspeakers to help installers deliver premium audio systems quickly and efficiently. They feature an intuitive browser-based user interface and a comprehensive set of algorithms to give installers confidence that their systems will perform as intended.
